Inspects and changes SQL schemas, queries, indexes, migrations, ORM data access, and MongoDB documents, queries, indexes, and driver pools. Use when editing SQL, migrations, schemas, indexes, ORM models or queries, or when the user mentions PostgreSQL, MySQL, SQLite schema design, Prisma, EF Core, Doctrine, SQLAlchemy, MongoDB, N+1, slow queries, pagination, or transactions. Redis and HTTP caching belong to caching.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
1. Identify the requested result and authorized database, schemas, environment, and role. For review-only work, inspect and report without applying changes. A reachable connection or generated command does not authorize execution. 2. Read the affected schema, migration history, query, and callers before editing. Establish engine, ORM, driver, migration-runner, and runtime versions from project metadata and the actual connection when available. Resolve version conflicts before selecting commands. Preserve the existing provider and major version unless their change is requested. 3. Load only the relevant procedures. - Read [PostgreSQL](references/postgres.md) for schema exploration, SQL semantics, plans, or index decisions. - Read [Prisma](references/prisma.md) for Prisma setup, commands, generation, or client code. Its command list applies to version 7 only. - Read [ORM review](references/orm-review.md) for generated SQL, loading, pagination, unit-of-work behavior, or concurrency. Read only the matching provider paragraphs. - Read [Migrations](references/migrations.md) before authoring or applying schema or data migrations, including ORM-generated migrations. …

How to install
mdr add dayfinggg/openai-codex-agent-skills/database@sha256:34c6bbfac1f12feeThe line at the top of this page pins the label git:20261105.e0d5bb2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
